FAQ

Emerson UPS power supply is mainly frequency machine or high frequency machine

Emerson UPS: Model: UL33 (20-60KVA), UL31 (30 to 80KVA), Hipulse U (80-400KVA) UHX (1-10KVA), UH31 (10,15,20 KVA), ITA (1-20KVA), NX series all models (NX are the beginning, 10-200KVA), APM (30-150KVA ), APL (300-800KVA) All modular UPSs are high frequency machines. (Low R & D cost is low, easy to manufacture), bulky, stable operation (internal bus voltage is relatively low, 450V below the DC), impact resistance load capacity is good, not Balanced load adaptability, the whole efficiency is low (less than 90% at half load), the battery hanging bus (battery charging capacity); High-frequency machine small size, light weight, high technical content (not easy to do high-power), bus voltage (700V or more DC), the unbalanced load and impact load tolerance is poor, the whole high efficiency (half The battery needs to be connected to the DC bus through a bi-directional DC-DC converter (ie, the battery converter) (the charging power is limited by the battery converter, up to 15% of the total power); The market is the largest machine sales Hipulse U and UL33, small machine ITA is currently selling very fire, the reason is very simple, buy big machine users focus on stability considerations, buy small machine users is to fight the price, buy cheap The Overall, Emerson's UPS is good, stable, user-friendly, very good quality, the price is on the side.

When the UPS load belt with more cases, in the absence of electricity when his duration will be short But if a UPS in the case of electricity, there will be no load too much, and over load, can not work properly?

If the UPS power supply capacity is nKVA, the output power factor is cosφ (conventional 0.7 or 0.8, depending on the load) 1. Then the UPS full load load is: n * 1000 * cosφ (W) 2. General UPS with 30% -70% of the load is reasonable, then the actual load with n * 1000 * cosφ * 0.7 (W) more appropriate. 3.UPS power load is too large will alarm, the use of the instructions will generally have a detailed description of different types of different brands of UPS overload capacity is not the same. Backup or online interactive UPS load is too large will alarm, and in the specified time automatically shut down the UPS output; online UPS load is too large will alarm, and in the specified time jump bypass, by the electricity directly for the Load power supply (if the load is short-circuit directly off the output, do not jump bypass).

Because the power failure, the company's financial department to buy two Hills 500i UPS Do you need to turn off the UPS after work? The Thank you Also after the power outage, the computer and other equipment is turned off, need to shut down the UPS?

UPS does not need to be closed every day. UPS uninterruptible power supply works as follows: AC-DC conversion: the grid to the AC power by the autotransformer step-down, full-wave rectifier, filter into a DC voltage, the inverter circuit. DC-AC inverter circuit: the use of high-power IGBT module full-bridge inverter circuit, with a large power margin, the output dynamic range of the output impedance is particularly small, with fast response characteristics. Due to the use of high-frequency modulation current limiting technology, and fast short-circuit protection technology, so that the inverter regardless of the supply voltage transient or load impact or short circuit, can be safe and reliable work.

What is UPS power supply? What is it for?

UPS power supply UPS is the uninterruptible power supply, simply in the city when the power outage can continue to provide uninterruptible power supply to a device to ensure that equipment can work properly. The simplest example is when you play computer at home, playing the game hot, but a sudden power failure, and if your computer is equipped with a UPS uninterruptible power supply, then even if the power outage can continue to play the game. There is a deeper role is to protect equipment and data security, this aspect of the UPS power supply will often be used in the hospital's precision instruments, the financial industry's servers, to protect some high-precision equipment from the quality of electricity (such as surge, Pulse, etc.), as well as protecting the data being transmitted, to prevent the risk of data loss, which is particularly important in the financial industry.

What is UPS? What's the role?

Said the simple point is that the power outage at home temporarily to the computer to provide normal work only 10 minutes to give you time to save or work safe to launch a charging period

First, determine the power section first Second, to confirm the UPS power section, we can choose the UPS work. Currently on the market more common way of work back-up, online interactive, online double conversion (line pure online) these three

Can put your device power w and delay request, ask me.

Summer voltage instability to buy a UPS-500 uninterruptible power supply, and now the voltage is stable, too troubles do not want to use this, and want to put up next year next year and then use. How does this store better? I heard there are batteries inside, so in terms of security, UPS is normal in the case of next year, this should be how to store. Please reply to a friend, thank you

Dry storage, the monthly discharge to keep the battery activity just fine

What is the relationship between this tile and kva?

10KVA UPS can take 6000 watts of electrical appliances. Depending on your power factor! In general, 10KVA high-frequency machine can take 7000W, frequency machine can take 8000W. But if you bring the electrical,
